UPPER UFFING MECHANISM FOR THE DIAPHRAGM FACE PLATES OF VESTIBULERAILWAY COACHES.

Application filed January 10, 1927. Serial No. 160,061.

- This invention relates to an improvement in an upper butling mechanismfor the diaphragm tace plat-es of vestibule railway ci'iaches, and hasfor its primary object the purpose of providing an improved resilientoperating device.

Another object ofthe invention in pro-` viding a bu'liing mechanism witha swivel action so that greater resilient flexibility is given theretoand to the diaphragm to which it is attached.

.il further object of theinventionis in providing a builing mechanism ota pair of toldable pushing elements.

Other and further objects will appear in the specification and bespecifically pointed out in the appended claims, reference being had tothe accompanying drawings, exempllrying the invention, and in whichFigure 1 is a plan view partly in section of adjacent ends of a pair ofcoaches having this improved butling mechanism attached to the end ofone of the coaches and the diaphragm.

Figure 2 is a vertical section taken approximately on the line II-II ofFig. 1.

Figure 3 is an enlarged horizontal section of the butling mechanismshowing it secured to the diaphragm and to the end of the coach.

Figure 4 is a fragmentary end view of a coach and the diaphragm iaceplate thereof.

teterriug by numerals to the accompanying drawings 1 and 2 designaterespective coaches and disposed between the ends ot said coaches are apair of diaphragm face plates E5 and 4 respectively and located beneaththe platform 5 of each coach is a pair of horizontally disposed pushingbars 6 each of said pushing bars being adapted to be moved outwardly bya coil spring 7 which is mounted on each of said bars, each of thesprings 7 is adapted to engage at one end against a collar 8 which isrigidly secured to each bar G whereas the opposite end of each spring isAadapted to engage against a cross member 9 which is mounted in eachcoach. The springs 7 each tend to push a respective bar 6 outwardly.

Each of the bars 6 at their extending ends are pivotally secured at 10between respective pairs of ears 11 which are horizontally extended froma pair of angle members 12, one of the members 12 being transverselysecured to the diaphragm face plate 3 whereas the other member 12 istransversely. secured to the diaphragm face plate 4 at the lower ends oisaid face plates. f

Each coach provided with a pair of doorposts 13 and secured to each postand to the side portions jlelol each of the diaphragm iace plates il andl is a foldable material 15, such as fabric, the 4foldablematerialextendmg upwardly the approximate height of `each of thediaphragm plates and joii1ing.with transversely disposed` portions ofmaterial 1G which are secured between the upper portion 17 of eachdiaphragm face plate and the car ends as designated at 18 in Fig. 2.Secured to the upper portion or cross member 17 of each of the diaphragmface plates 3 and a is a bracket 19 and formed on each bracket arehorizontally disposed pairs of ears 20 and pivotally secured at 21between each pair of ears is a push rod`22, each of said push rods beingoppositely disposed and are each mounted in a respective cylinder 23each of said cylinders having an end wall 24 through which the extendingend of a respective push rod is passed and mounted oli each extendingpush rod end is a holding nut 25.

Each of the cylinders 23 at its closed end is provided with a lug 26,eachof said lugs being pivotally secured on a pin 27 of a respectivebracket 28, said brackets being secured to the respective ends ofthe-coaches 1 and 2.

Each of the push rods 22 is provided with a rigidly secured collar orshoulder 29, each ot said collars being disposed in a respectivecylinder 23 and are adapted to slightly engage the interior wall of saidcylinder, and.

mounted on each rod 22 of each cylinder is a coil spring 30 each olsaidsprings at one end adapted to engage the end wall of Ia respectivecylinder whereas the opposite end of each of said springs is'adapted tobear against a rgspective collar 29 of each push rod 22.

Each angle member 12 of each coachl is 1ocated outwardly of each crosssill 31, and secured to each member 12 is a horizontally disposed apron32, each apron at one end resting on the platform 5 oi each respectivecoach.

Then a pair of coaches are coupled together as shown, the diaphragm faceplates 3 and el are held in abutting relation by reason of the action ofthe springs 7 on respective push rods 6 and the springs 30 on thepushing rods 22 and in which the foldable connecting material betweenthe diaphragm face plates and respective coaches wiil be expendedthereby providing,` zi cioeed paesuge between the coaches.
